XPARTCO W10804664 Washer Motor Run Capacitor (50µF)
The XPARTCO W10804664 is an aftermarket replacement motor run capacitor for Whirlpool-built top-load washers. This capacitor works alongside the washer's motor to help it start and run efficiently — it briefly boosts the voltage delivered to the motor at the moment it's commanded to start, giving it the extra push needed to overcome its own inertia and begin turning smoothly. Once the motor is running, the capacitor continues supporting steady, efficient operation for the duration of the cycle.
Rated 50 MFD (µF) at 250VAC. Over time, the dielectric material inside a run capacitor breaks down from repeated startup stress and heat cycling, which reduces its effectiveness or causes it to fail outright. A failing capacitor produces a clear symptom: the washer motor hums but won't start, or the motor makes noise during use without turning properly. Left unaddressed, a struggling motor can also run hotter than normal and wear out faster than it should. It directly replaces W10278117, 4247711, W10666221, W10804664VP, AP5982844, EAP11703494, and PS11703494.
Quick Answer
The XPARTCO W10804664 Washer Motor Run Capacitor fixes Whirlpool, Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Crosley top-load washers where the motor hums but won't start, or makes noise during use without running properly. Rated 50 MFD (µF), 250VAC. Replaces W10278117, 4247711, W10666221, W10804664VP, AP5982844, EAP11703494, PS11703494. Capacitors store a dangerous electrical charge even after power is disconnected — always discharge before handling.

Note: Whirlpool uses several different washer motor run capacitors across its platforms with similar-looking part numbers but different MFD ratings — for example, other listings cover 45 MFD (W11158830/W10625045) and different 50 MFD variants (W11395618/W10625046) used on other washer model families, none of which are interchangeable with this 50 MFD/250VAC W10804664. Always verify your full model number and match the MFD rating printed on your original capacitor before ordering. Contact our support team with your model number if you're unsure.

Installation Notes
⚠️ Danger — Capacitors Store A Dangerous Electrical Charge Unplug the washer or shut off the house circuit breaker before beginning. A capacitor stores an electrical charge even after power has been disconnected, and that charge can deliver a serious or fatal shock. Before touching either terminal, discharge the capacitor by shorting its two terminals together using an insulated-handle screwdriver, or by using a proper capacitor discharge tool with a resistor. Never short the terminals with a bare metal tool held with your bare hand. If you are not fully comfortable performing a capacitor discharge safely, have a qualified appliance technician replace this part instead.
⚠️ Shut Off Hot And Cold Water Supplies Before Starting Wear work gloves. In addition to disconnecting power, turn off the hot and cold water supplies before beginning disassembly. Access to the capacitor typically requires removing the washer's console and outer body panels — remove the mounting screws and release any spring clips securing the body to the frame, using a putty knife to gently pop them free. Locate the capacitor, usually mounted to the rear panel or motor bracket area. Photograph the wiring before disconnecting anything. After confirming the capacitor is fully discharged, disconnect the wire terminals from the old capacitor, remove its mounting clip or bracket, and pull it free. Install the new W10804664 capacitor in the same position, reconnect the wire terminals, and secure it in its mounting clip or bracket. Reassemble the body panels, spring clips, and console in reverse order. Restore water and power, then run a test cycle through both agitate and spin, confirming the motor starts promptly without humming or hesitation. Tools needed: putty knife, Phillips screwdriver, insulated-handle screwdriver or capacitor discharge tool, work gloves.
Frequently Asked Questions
My washer motor hums but won't start. Is this the right part?
Yes, this is the classic symptom of a failing run capacitor. Since this capacitor's job is to boost voltage to the motor at startup, a weak or failed capacitor can leave the motor energized and humming without ever getting the push it needs to actually begin turning.
How do I know I have the right MFD rating for my washer?
Check the rating printed directly on your original capacitor's body — this listing is specifically 50 MFD at 250VAC. Whirlpool uses several different run capacitors across its washer platforms, including a 45 MFD version and other 50 MFD variants with different part numbers, and installing the wrong rating can leave the motor under- or over-supported. If you're not sure, contact our support team with your model number.
Do I need to shut off the water supply just to replace a capacitor?
It's a precaution taken because accessing this capacitor typically requires removing the washer's outer body and console, which involves working around the same general area as the water inlet connections. Shutting off the water first prevents any accidental spills or pressure issues while the body is open, even though you won't necessarily be disconnecting the water lines themselves for this specific repair.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Whirlpool OEM part, but is manufactured to match the 50 MFD, 250VAC electrical rating and mounting configuration of the original W10804664 run capacitor used in compatible Whirlpool, Maytag, KitchenAid, Jenn-Air, Amana, and related top-load washers.
